Abstract

Insulating element from mineral fibers for shipbuilding with an insulating element in form of a plate or roll felt for shipbuilding the composition of the mineral fibers of the insulating element points an alkali/alkaline-earth mass ratio of the fiber structure of the insulating element is determined by an average geometrical fiber diameter of ≦4 μm and a surface weight of 0.8 through 4.3 kg/m2 and a binding agent portion above 0.5 until 4 weight %.
